Thanks for that link,a song sung in English by apparently a Japanese vocalist-—never heard it before and not sure what you intended by posting it in this thread, except for the (to me)obvious one.
I'd bet on Korean, given the letter-shapes in the title. Here's a Japanese-singing-English song: I'm yours.
Bonus 1: Japanese version of a good English song - Wonderwall.
Bonus 2: Japanese American Utada Hikaru singing Boulevard of Broken Dreams. Bonus 3: An excellent rendition of an English-speaker singing in Japanese rendition of Fireflies.
